Safety Approvals
Design for Environment
Meets requirements in high-temperature
lead-free soldering processes.
The PKV series of DC/DC power modules is intended for
general use in 12/24 V and 48/60V DC systems. Designed
with MOSFET transistors and 200 kHz switching fre-
quency, they are characterized by high efficiency over a
wide load range, very low quiescent power and an excel-
lent line and load regulation.
The DC/DC power modules are encapsulated in an ep-
oxy filled plastic box. The flammability ratings of the en-
capsulating materials are in conformance with UL 94V-0
and have an adequate thermal conductivity. The materi-
als withstand all normal PBA cleaning methods. Ericsson
Power Modules is an ISO 9001/14001 certified supplier.

Safety
The PKV 3000 I and PKV 5000 I series
DC/DC converters are designed in
accordance with safety standards
UL 60 950-1,
Safety of Information
Technology Equipment.
The PKV
3000 I and PKV 5000 I series DC/
DC converters are UL 60 950-1
recognized. The DC/DC converter
should be installed in the end-use
equipment, in accordance with
the requirements of the ultimate
application. The input source must be
isolated by minimum Basic insulation
from the primary circuit in accordance
with UL 60 950-1. If the input voltage
to the DC/DC converter is 72 V dc or
less, then the output remains SELV
(Safety Extra Low Voltage) under
normal and abnormal operating
conditions.
It is recommended that a slow blow
fuse with a rating of 2 x I
I
max be used
at the input of each DC/DC converter.
If a fault occurs in the converter that
imposes a short circuit on the input
source, this fuse will provide the
following functions:
• Isolate the faulty DC/DC converter
from the input power source not to
affect the operation of other parts of
the system.
• Protect the distribution wiring from
excessive current and power loss
thus preventing hazardous overhea-
ting.
The galvanic isolation is verified in an
electric strength test. The test voltage
(V
ISO
) between input and output is 1500
Vdc for 60 seconds. Leakage current is
less than 1µA at nominal input voltage.
The flammability rating for all
construction parts of the DC/DC
converter meets UL 94V-0.

Stress in excess of Absolute Maximum Ratings may cause permanent damage. Absolute
Maximum Ratings, sometimes referred to as no destruction limits, are normally tested with
one parameter at a time exceeding the limits of Output data or Electrical Characteristics.
If exposed to stress above these limits, function and performance may degrade in an
unspecified manner.
